场解吸质谱(field desorption mass spectrometry,简称FDMS)是近十年来发展起来的新技术,由于它能测定一些用电子轰击质谱难以得到分子离子峰的极性化合物,故特别受到人们的重视。我们曾利用MAT-711质谱仪,采用FDMS法成功地分析了糖甙及磺酸盐等化合物,并对糖甙混合组分进行了测定。 1.糖甙类化合物的测定:以腺嘌呤核苷(adenosine),槲皮素,原人参三醇甙(ginsenoside Rg_1)和β-甲基地高辛~*为样品,在最佳阳极温度条件下录谱,均 Field desorption mass spectrometry (abbreviated as FDMS) is a new technology developed in the past ten years. Because it can determine some polar compounds that are difficult to obtain molecular ion peaks by electron bombardment mass spectrometry, it has received particular attention. We used the MAT-711 mass spectrometer to successfully analyze compounds such as glycosides and sulfonates using the FDMS method, and measured the components of the glycocalyx mixture. 1. Determination of glycosides: samples of adenosine, quercetin, ginsenoside Rg_1, and β-methyl digoxin were taken at optimal anode temperature conditions. Recordings, both
